  • Patent number: 11205910
    Abstract: The invention relates to a method for charging or discharging an energy store (2) with at least one cell block (20) consisting of multiple series-connected battery cells (3-7) by means of a series charging current (IO) flowing through all battery cells (3-7), wherein at least some of the battery cells (3-7) can have different capacitances (CN). In order to permit a reliable and quick charging of energy stores, the invention proposes measuring the capacitances (CN) of the N battery cells of the cell block at regular time intervals, and determining a maximum charging current for each battery cell based on the measured capacitances and a predefined C-factor (ratio of the maximum charging current IN;max to the capacitance CN) for each battery cell. With these maximum charging currents, the battery cells are then simultaneously charged during a charging time t (t?1/C) predefined by the C-factor.
